Graduate / "the knowledge of instrumentation and signal processing" -need help with sop writting [3]

i have started writing my sop but i am not sure whether i am going in the right in the direction or not so please can some body help me.this is the starting para.

I want to reach the summit in the knowledge of instrumentation and signal processing , apply this knowledge for the innovation of new technology which could benefit and lead to the betterment of human life.with this goal in my mind i did both my bachelors and Masters from biomedical engineering.I would like to quench my thirst for knowledge by reaching one more level.My quest till now would not have been possible without support of my family,teacher sand friends and i am thankfull to all of them.As a child i saw a documentary about artificial heart ,how it proved to be life saver for a patient who was on death bed.This fascinated me a lot and led to the strong desire of becoming a biomedical engineer.
